Reference is had to the accompanying drawings which illustrate the preferred form of the invention; though'it is to be understood that the invention i snot limited to the exact details of construction shown and described, as it is obvious that various modifications thereof within the scope of the claims will ocour to persons skilled in the art.

provision ofmechanism for operating car brakes, which may be manipulated from the top of the car or from the side thereof.

Another object of this invention is the provision of a gearing device for actuating railway car brakes, and an interchangeable operator therefor whereby the gearing device maybe actuated either from the side of the car or from the top thereof, as desired.

A further object of the present invention.

is the provision of novel gearing mechanism for actuating the brake mast, and also the provision of novel mounting means'for said gearing mechanism.

More particularly this invention contemplates the provision of a gearing mechanism and mounting therefor, for actuating railway car brake masts; said gearing mechanism being so formed as tobe operable by an interchangeable lever, which, in effect, forms a partof the brake mast,-whereby said gearing may be actuated either from the side of the car or from the top thereof.

. Other objects and advantages of this invention will be apparent from the following description taken with the, accompanying taching plate 6 secured to the undersurface.

of the step plate by suitable fasteners such as rivets 7, and a supporting plate 8 depending therefrom and having its lower end formed into a bearing part 10 of a two part bearing, the other part of which is designated at 12 and being secured to the part 10 by bolts 14 or the like. The two part bearing is, in efi'ect, a housing, the sections 10 and 12 of which are provided with alining guide ribs 16 which engage in an annular recess 18 formed in the hollow hub 20 of a bevel ear 22 whereby to retain the gear in said housing.

The attaching plate 6 is provided with a tubular boss 24 which extends through the step plate as clearly shown in Fig. .3 and which serves as a guide or hearing to mount a pawl 25; the latter being restrained against displacement by a keeper 26 mounted on a bolt 28 secured in the tubular boss 24 by a' nut 30.

The attaching plate 6 is further provided with a guide 32 which extends upwardly through the plate 4' and downwardly there'- from, into" which the hollow hub 34 of a bevel gear 36 extends; said gear being arranged to mesh with the before mentioned gear 22, and being mounted 'on'a shoulder 38 formed adjacent the reduced end 40 of a brake mast 42, the latter beingsuppo'rt'ed by a stirrup 44 secured to theend sill, and having a winding drum 45" at its lower'end'.

For eliecting rotation of the brake mast.

42 by the gear 36, the inner surface of the hub 34 is preferably squared and the reduced end 40 of the brake mast is correspondingly squared. The brake mast-42 is rotated by an operator 46 having'a reduced squared end 48 extending into thehub 34 as clearly shown in Fig. 3. This operator is, in effect, an extension of the brake mast 42 when assembled with the gearing mechanism as illustrated in Fig. 3, and indeed, the brake mast may well be considered as being formed of two parts, namely, 42 and 46, said parts or sections be ing connected together as just described.

The brake mast section or operator 46 extends upwardly as shown in Fig. 2, beyond or above the top of the car and is provided with a hand wheel for operating purposes.

' The section 46 is restrained against displacement as now tobe described, and referring to Figs. 8 and 9, a bracket 54 is secured to the top portion of the car, which'bracket is provided with a substantially circular aperture in which is seated or positioned a hearing guide 56, through which the brake mast section 46 extends; the guide being secured to said section by means of a set screw or the like. For preventingvertical movement of the brake mast section 46 or the guide 56 or both, said guide'is provided with an annular shoulder 62 which, when the parts are assembled, bears againstthe under surface of the bracket 54(see Fig.9). Communicating with the aperture in which the guide is positioned is a slot 64. This slot is necessary in view of the fact that when disassembling the device, the set s'crew. 60 is loosened thereby permitting the guide 56 to drop away from the bracket 54 and the brake mast section 46 may then be removed from the bracket 54 through the slot 64.

A ratchet is secured to the lower end of the brake mast section 46 by means of a key 68 seated in a longitudinal recess 70 formed in the mast section 46. The ratchet is'provided with'a hub 72 with which the The brake mast section 46 is adapted to be.

attached to or assembled with the bevel gear 22 when it is desired to actuate the gearing mechanismfrom the side of the car, as il-.

lu'strated in Fig. 4, and' for supporting-the brake mast section 46,- a bracket 74 is secured to theend sill B adjacentv the side of the.

car. The bracket 74 is more particularly of thQ'fOIIIl shown in Fig.2, and is provided withspaced arms 76 forsupporting the bear-:

ing guide 56 through which the mast section:

46 extends, and the reduced end 48' of the of bevel gear 22 whereby toactuate th'egear in an obvious manner. A p i The supporting plate 8 depending from the attaching plate 6 is provided with an integral bearing 80 through which extends.

brake mast section exte'nds into the hub 20": o

the reduced end 82 of a pawlactuating lever 1 84, the opposite end of which lever is jour,

naledin the bracket 74, as clearly shown in Fig. 2,'and said leveris provided withan opera-ting handle 86 whichis normally supported on a stop 85 formed with the bracket 74. The lever 84 is retained against displace ment by a nut 88 and the reduceden'd 82 defines a shoulder to limit the positioning of said lever against the outer end of the bearg I ing, 80, as will be apparent. .As shown clearly in Fig.6, suitable washers 96 arepro= vided for an obviouspurpose. The'beari'ng 8O isprovided' with an an nularshould'er 92 and a pawl 94 is mounted onthe shoulder; the shoulder limiting the. inward movement of the pawl.

the pawl from the lever 84, the latter is provided with an angletongue 96 the end of which is engaged in an aperture 98 formed in the pawl, and said pawl is so arranged on Or actuatingthe plate 8 as to engage the teeth of the ratchet 66. I

It is believed that the construction and operation of the device described" will be fully apparent to those skilled in the art, but at tention is called to the fact that the said device, more particularly the gearing mecha-r v nism thereof, is adapted to be actuated either from the side of the car or from the top,

thereof. When actuating the device from the top of the car, the parts are in thepos'i tion shown in full lines in Fig. 1, and it will be obvious that operation of the hand'wheely drop the bearing guide 56 from the aperture in. the plate 54, whereupon the upper brake mast section 46 may be removed from the plate 56 by passing it through the slot 64. The brake mast section 46, together with the hand wheel, and bearing guide, and the ratchet 66 may then be applied to the side of the car by first inserting the reduced end of the brake mast section 46 into the hub 20 of the bevel gear 22. This will position the ratchet 66 so as to be engaged by the pawl 94. The upper end of the brake mast section 46 is then arranged between the spaced arms 76 of the bracketand the bearing guide 56 then arranged between said arms in a mannersimilar to that shown in Fig. 9, and the set screw 60 adjusted to secure the bearing guide and brake mast section46 together. It will be apparent now that opera tion of the hand wheel will directly rotate the bevel gear 22, and consequently, the gear 36 and the lower brake mast section 42, to

1 actuate the brakes, and the brakes may be retained in desired adjusted position by .means of the pawl 94 and the locking tongue What is claimed is 1.
